Detailed Answer
Zero-position protection means the control mechanism must be in the zero position (no operation) at the moment of startup, otherwise startup is refused by the control logic. When powered on, an industrial remote control checks that all buttons are in the released (zero) position; if a button is detected as pressed, startup is blocked and an alarm sounds, preventing accidental actuation at power-on. Both the LIDER LD series and XINGJIA series are equipped with zero-position protection, which together with the emergency stop and key switch forms a complete safety system.
| Principle | Check zero position at power-on |
| Function | Prevents accidental actuation |
| Config | Standard on LIDER/XINGJIA |
Note:After power-on, first confirm no button is stuck, then start operating.
